Rubber Products
Pipe and Spool
Rubber lined pipe is an effective solution for protecting piping systems from corrosion and abrasion. With advanced rubber lining technology, this product not only ensures durability but also extends the lifespan of pipes in various industrial applications.
Characteristics
- ( 01 )
Chemical resistance and abrasion resistance
The rubber lining has resistance to many types of chemicals, including acids, alkalis, and solvents, helping to protect pipes from chemical corrosion. With high durability, this rubber layer can withstand impacts from solid particles or corrosive liquids, minimizing the risk of damage. - ( 02 )
Excellent adhesion
Advanced bonding technology ensures that the rubber layer firmly adheres to the pipe surface, minimizing the risk of peeling during use. - ( 03 )
Noise and vibration reduction
The rubber layer has noise and vibration absorption properties, significantly reducing noise generated in the piping system, creating a quieter working environment. - ( 04 )
High durability
Thanks to superior corrosion and abrasion resistance, rubber-lined pipes have a longer service life compared to conventional pipes, saving maintenance and replacement costs during operation.
Workflow
The application process for Pipe and Spool includes the following steps:
- STEP 01
Surface Treatment
To ensure a clean metal surface that meets standards, the pipe undergoes sandblasting, completely removing rust, pigments, and old coatings. After sandblasting, the surface is thoroughly inspected to ensure it meets technical requirements.To ensure a clean metal surface that meets standards, the pipe undergoes sandblasting, completely removing rust, pigments, and old coatings.

Primer/ Bond Coating
After cleaning, a special primer is applied to enhance adhesion for the rubber lining. Next, an appropriate adhesive is used to ensure the best bond between the rubber lining and the metal surface. Additionally, another primer layer may be applied to enhance protection and adhesion.After cleaning, a special primer is applied to enhance adhesion for the rubber lining.

Rubber Lining
The rubber is cut to appropriate dimensions and securely wrapped around the agitator blade surface. This process must be performed carefully to eliminate air pockets between the rubber and the surface.The rubber is cut to appropriate dimensions and securely wrapped around the agitator blade surface.
